My '90 22R (4spd manual/Carb/ RWD- not my 4x4) is leaking about 8 drops of engine oil per night (10-12 hour period) It's definitely engine oil, coming from right under the engine. The 22R is otherwise solid, not tired at all, great power/ torque, smooth & quiet. Currently at 175k on original engine/ tranny. How would I find the source? What are some common leaks on these? I don't really want to start tearing it up to check- I don't mind the small leak, but it would be nice to get rid of. How about that "rear main seal repair in a bottle" stuff? If I found the source of the leak, could I put something on it externally? (ie: JB Weld, RTV, etc.) Any ideas/ suggestions?

Thanks!

 

Start by cleaning the motor. Clean all the oil off.

Then check where the leak is coming from.

And whatever you do, DON'T use that seal-repair in a bottle crap. If its designed to block oil from leaking, its going to block oil from flowing.

 

Cool. I'll degrease it. Is it ok to use a pressure washer?

 

just get some purple power and a rag and wipe it off under there
